WELL-PUMP TUBING.

SPECIFICATION forming part of Letters Patent No. 317,557, dated May 12,1885.

Application filed August 2l, 1884.

To a/ZZ whom, it may concern:

Be it known that I, Josnrn MARsDnN, a citizen of the United States, anda resident of Far Itockaway, in the county of Queens and State of NewYork, have invented certain new and useful Improvements in Well-PumpTubing; and I do hereby declare that the following is a full, clear, andexact description thereof, which will enable others skilled in the artto which it appertains to make and use the same, reference being had tothe accompanying drawings, which form a part of this specification, andin which-- Figure 1 is a vertical sectional view of my improvedwelltubing, and Fig. 2 is a perspective view of one of the tubes orpipes with a portion of the same broken away for the purpose of showingthe invention more clearly.

The same letters refer to the same parts in both the gures.

This invention relates to well-pump tubing, and more particularly to thejoints of the same; and it has for its object to construct the saidjoints in such a manner that the sections of tubing shall thereby beeasily set 7 or connected together in such a manner that they cannotaccidentally be dislocated or pulled apart, and in such a manner as torender the said joints tight and water-proof.

Vith these ends in view my invention consists in the improvedconstruction and arrangement of parts, which will be hereinafter fullydescribed, and particularly pointed out in the claims.

In the drawings hereto annexed, A designates a section of my improvedwell-pump tubing, which may be constructed of earthenware, or of anyother suitable material, and which consists of a cylindrical tube, B,one end of which is enlarged inthe usual manner, as at O, for thereception of the end of the next adjoining section. The enlarged end orcollar C is provided on its inner side with an annular groove,l D,corresponding Vwith an annular groove, E, formed upon the outside of thesmall end of the cylindrical portion B of the tube. The inner side ofthe said small end is beveled, as at F, to correspond with a beveledannular projection, G, formed at the other end of the tube within thecollar O.

H designates a metallic cap, which is fitted (No model.)

over collar C of the top pipe, and which serves to connect thereto anipple-joint, I, which forms the pnmp-connection. f

The operation and advantages of this invention will be readilyunderstood from the foregoing description, taken in connection with thedrawings hereto annexed.

It should be noted that the interior diamethe exterior diameter of thesmall end of the pipe. Owing to this construction, the pipes are easilyset in position, and guided to proper position by the beveled projectionG, entering and engaging the bevel F, as clearly shown in Fig. 1 of thedrawings. In this manner a smooth an'd tight joint is formed, which is.fills the grooves `D and E, thus serving not only to form a waterproofconnection, but also to bind the pipes together very securely.

My improved well-pump tubing is simple in construction and inexpensive,and the improvements described are capable of being successfully appliedto tubing of small diameter, thus enabling me to effect a considerablesaving in the expense of boring.

Having thus described my invention, I claim and desire to secure byLetters Patent of the United States- 1. As an improvement in well-pumptubing, a tube-section having at one -end an interiorly-grooved collar,and at the other end an exterior annular groove corresponding with thegroove in the said collar, substantially as and for the purpose setforth.

2. As an improvement in well-pump tubing, a tube-section having at oneend a beveled projection surrounded by an enlargement or collar, andhaving `its other end interiorly beveled to correspond with the saidbeveled projection, substantially as and for the purpose set forth.

3. As an improvement in well-pump tubing, a tube-section interiorlybeveled and exteriorly grooved at one end, and having its other endprovided with a beveled projection surrounded by an interiorly-groovedcollar or enlargement, substantially as and for the purpose set forth.
